Lever Sign Test for ACL Injury (ptpodcast.com)

• Alessandro Lelli described the Lever Sign test in 2014 claiming 100% accuracy
• First independent study shows high but not perfect sensitivity and specificity
• Test serves as adjunct to Lachman and Pivot Shift tests

"The Lever Sign test, originally described by Alessandro Lelli, claimed 100% accuracy for ACL rupture. A first independent study now examines this claim. The test involves lifting the patient's lower leg while supine, with a positive sign indicating ACL insufficiency. The study compares sensitivity and specificity against established tests like Lachman and Pivot Shift. Early results show high but not perfect accuracy."
